This invention relates to a novel improvement in mining machine trucks, adapted for transporting'andV maneuvering al mining machine beyond theend'of' a mine track, as' for instance, along therloor ofal mine room. A further obgect ofV the invention is to provide a truck sui'liciently lowiny order that a mining `machine may be propelled about mine rooms in mines where the coal seams are relatively thin. Another V'object is to provide the truck withl steering rods outside thereof, to enable the loading and unloading of the mining machine without interfering withy the steeringl mechanism.

The invention willV best be understood by reference to the accompanying drawings, in which: f Figure l is atop plan view of a truck with the mining machine removed there?v from, andV illustrating the steering device arrangement Figure 2 is a'viewf of the truck'in side ele'- vation, showing a mining machine thereon in dotted lines ;k

ing machine and truck may be readily transported, but in a great number of instances, itis desirable to transport the mining machinea considerable distance beyond the end of the tracks, up to the working face, las for example in vmines where itis notv vdeemed advisable or economical to extend temporary tracks into such mine rooms. ln such cases it has heretofore been necessary to unload the mining machine from the truck at the entrance to the rooms, and drag it bodily to the working face by means of crow bars or thel like, or by power driven draft ropes carried by the"y machine, and' anchored at a In carrying out my presentl invention, l provide a truck mounted on suitable tractor type wheels and including an improved steering device,y which permitsl the mining deliveredv to the working face, over mine floors without tracking, vand to be guided or turned at will forloading or unloading the mi-ningmawherescraper loading units are used, and

the extension of tracks in the rooms therefore rendered impossible under usual mining conditions, vSince the truck is especiall r equipped forV maneuvering on mine floors without tracking, it is possible to travel both to and from the vorking face, or to a break through in mine rooms, and also in case oi necessity toa convenient out of the way location, Ythereby 'permitting the scraper loading element to remain in position in the ,room neck on' the track.

TheV ruggedness and durability of construction,'in conjunction with the simplicity of operation, dled with ease.

Referring now i-n detail to the drawings, a vmining'machine truck is indicated at l, provided with a body portion 2, having a pair of longitudinally disposedside mem bers 8, 8, attached thereto, acting as guides when loading and unloading a mining machine. Said body portion is provided Vwith permits the truck to be han- Y posed inside of Y1e g 'when said mining the usual drop front 4, pivotally supported at the forward end thereof to receive amining machine 11 (see Figure 2) of the usual t e which is drawn Vu on said drop front YP P on to the truck by means ofrits draft ropes in the usual manner. The rearward portion of said body is provided with apair of Suitable tractor type rear wheels 5, 5,' disuards 6, 6, which have rigid connection to the sides of the body. Each of said combination frames and guards are provided with a pair of internal hub projections 7 '7, on the sides thereof, adapted to. support transversely disposed stud axles 8, Y8 A pair ofsprockets 10, 10 are fixedv to rotate n u and drive the rear wheels 5, 5. Said vsprockets are `operatively engaged through suitable chains 13, 18, to a second pair of drive sprockets 14, 14, forming part of the usualtruck driving mechanism generallyindicated atGO Vadapted to be driven by a motor 12 of the mining machine 11 through a coupling pin 12a in the usual manner machine is. mounted on the truck. SaidY truck driving mechanism comprises a worm 61 driven by the coupling pin 12a which in turn drives a worm wheel Y 62 on a shaft 63 for driving the sprockets From the foregoing explanation it may readily be seen that the said rear Wheels receive the necessary power to propel the said "truck about the mine room.

disposed screw 20. The unthreaded portionv of said screw is afforded support forward of said steering wheel by means of a iianged journal 21, substantially secured by suitable means to an angle iron 22, which herein forms the rear end of said truck body. A collar or Vspacer 23 is looselyimounted on the screw intermediate the said hub eXtension of the steerling wheel and said flanged journal. A trunnionv nut 24, having threaded engagement on said screw, is provided with a pair of stud projections 25, 25, formed integral with said nut, and disposed in opposite relation to each other, and on the vertical aXis of said trunnion nut. Said stud projections engage apertures in the trunnion nut the combination frames and bracket 28, and in the steer.

ing beam 29, respectively. Said trunnion bracket and steering beam are provided with suitable depressions 80, V30, at a point in line with the trunnion nut, so as to form a guide to prevent radial movement ofthe trunnion nut about' the vertical axis Vof the stud projections.

` rihe steering beam is transversely disposed and pivotally mounted on aA pivot pin 31, on the longitudinal center line at the rearward end of the truclr, intermediate a tongue extension 32, and an angle clip support 38. Said tongue and angle clip are rigidly secured to the angle iron at the rear of said truck, and are vertically spaced by a shim or filler bar 84, to provide free rotatable movement of Vthe steering beaml about said pivot pin. n

The various members of the steeringV apparatus on each side ofthe trucl; are similar in construction and operation, therefore the description and numbering of the parts for one side wili suffice and apply to both.

The end portions of the steering beam project beyond the lateral sides of the truck. Each of the end portions areprovided with an offset portion 35. attached atl the end of said steering beam directly over the forming a clevis. Said clevis is provided with a pivot pin 87 depending therethrough and pivotally securing therein the flattened end portion 88 of asteering 'rod 39,. vSaid steering rods are longitudinally disposed outside of the Ylateral boundaries of the Y truck to thatvthe height kof the truck may be'kept at aV minimum. The forward end of said steering rod and is Vsupported in a clevis 41, of a clevis nut 42. The forward end 40 is pivotally mountedon a pivot pin 43 in said clevis.V The clevis nut is provided with a recess 44k on the side opposite the clevis. The recess of the clevis nut isinwardly threaded for engagement on the threaded portion of a front axle 45. Said front axle isformed integral with the axle bracket 46. The

offset portion, thereby is also flattened at 40,

A strap 36 is suitably i front axle is provided with a loosely mounty y ed tractor type wheel47, `forming the front supporting wheels for the truck.

The axle braciret is provided with a vertical boss portion adapted vfor pivotaliy mounting Vbetween a pair of horizontally disposed lug projections 50, 50, by, means of a pivot pin 51, which is rigidly securec t said boss portion.. y The pivot pin lris perinitted to freely rotate in said lugs, thereby Y affording free turning of the entire wheel and axle. The lug projections are formed integral with a frame bracket 58, which is rigidly secured to the body .of said truck.

On the upper end of the vertical sides of said body, I provide studs 54, 54, verticallv disposed rearward ofsaid steering beam, als a means to limit the radial movement of instant the'steerin'beam and thereby reventinv C) 7 u C either oi" said 'front Wheels from striking rvparts may be altered Without departing from the spirit and scope thereof. I do not therefore Wish to be construed as limiting myself to the specific construction illustrated herein excepting as may be specifically limited in the appended claims.
